| Abstract: | A numerical simulation with FEM model comprising point surface contact element was provided on large diameter and super long bored piles in Sutong Yangtze bridge.An analysis and validation were given for this FEM with test data of pile in Jiangyin Yangtze bridge.The result shows that this FEM numerical simulation method comprising point surface contact element is a reliable method,and it can simulate large deformation between pile and soil,and provide an evidence for the design of piles foundation. |
